Résumé
The Environmental Protection Agency (EPA) is proposing to approve, as a revision of the California state implementation plan (SIP), the State's request to redesignate the Yuba City-Marysville nonattainment area to attainment for the 2006 24-hour fine particulate matter (PM 2.5 ) National Ambient Air Quality Standard. EPA is also proposing to approve the PM 2.5 maintenance plan and the associated motor vehicle emissions budgets for use in transportation conformity determinations necessary for the Yuba City-Marysville area. Finally, EPA is proposing to approve the attainment year emissions inventory. EPA is proposing this action because the SIP revision meets the requirements of the Clean Air Act and EPA guidance for such plans and motor vehicle emissions budgets.
